In plain English

This was a two-page editorial, not an original study. The author commented on a separate study by Larson and colleagues, published in the same issue of Radiology. That study looked back over series of chest radiographs of selected former vermiculite miners and millers from Libby, Montana, who had been exposed to amphibole asbestos. According to the editorial, Larson and colleagues found substantially shorter latencies for asbestos-related pleural disease than previously reported. They also found that pleural plaques could be seen in retrospect on earlier images once they had been confidently identified. The editorial gave no numbers from that study. It reported that in that cohort no measures of exposure predicted progression of pleural or parenchymal disease. The author noted this could be due to the small number of subjects, or that host susceptibility factors may play a role. The author stated that whether the findings apply to other asbestos exposure settings awaits further investigation. The author concluded that further refinements in the use of simple imaging tools for medical surveillance remain essential.

What the study did and found

• Design: Editorial (commentary) on another study, Larson et al, Radiology 2010;255(3):924–933; no original data
• Who was studied: No one was studied by the author. The editorial discusses Larson et al's study of selected former vermiculite miners and millers from Libby, Montana.
• Exposure: Amphibole asbestos (Libby amphibole) from vermiculite mining and milling in Libby, Montana, as described for the Larson et al study
• Main results:
  • The editorial reports that Larson et al found substantially shorter latencies for asbestos-related pleural disease than previously reported (no figures given in the editorial)
  • The editorial reports that, in the Larson et al study, pleural plaques identified on a chest radiograph could often be seen in retrospect on earlier images
  • The editorial reports that in the Larson et al cohort no exposure measures were found to predict progression of asbestos-related pleural or parenchymal disease
• The authors' conclusion: The author concluded that further refinements in the use of simple imaging tools for medical surveillance remain essential
• Limitations the authors state:
  • The author noted that the lack of exposure predictors of progression in Larson et al could be due to the small number of subjects, or alternatively that host susceptibility factors play a role
  • The author stated that whether the Larson et al findings apply to other asbestos exposure settings awaits further investigation
